This strongly bitter herb has been utilized for a long time as a folk medicine.
An herbal tea made from the leaves has been used traditionally for irregular menstruation, to strengthen appetite, increase the secretion of digestive fluids, indigestion, and enhance nutrient absorption.
Bogbean is closely related to yellow gentian (Gentiana lutea) and contains similar bitter glucosides though it is far less bitter than both yellow gentian and centaury (Centaurium erythraea).
Like yellow gentian, the bogbean leaves also contain various tannins and flavonoids and should be used with care to avoid irritation of the gastrointestinal tract.
Bogbean is generally used in conjunction with other medicinal herbs.
Ailments like dry cough, fever, migraine, gout, arthritis (rheumatoid arthritis), rheumatism, heartburn and muscle weakness associated with chronic fatigue syndrome have also been treated with the herb.
It has been used as an external remedy for wounds, for skin rashes, inflammation, itch, eczema and edema.
